Patent GB-488583-A (GB)
Title: Improvements in automatic switches for use in telephone or like systems
IPC: H01H67/16
Filed: 1937-01-11
Abstract: 488,583. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., BEALE, C. E., and RICHARDS, I. T. Jan. 11, 1937, No. 853. [Class 40 (iv)] A two-directional switch having two magnets only and released over the setting path by a further operation of the vertical magnet after vertical and rotary movement as described in Specification 399,815, is provided with circuit arrangements such that release always takes place in this way whether after conversation or when used as a drop-back selector in response to a critical digit to connect up a different set of wipers, or on a prematurely abandoned call. When the switch is seized, relays A, B, ON, C operate, and dialling tone from lead 11 is supplied over a balanced circuit. At each impulse, relay B is short-circuited and the vertical magnet VM operates over resistance YB and the upper winding of relay C. When the switch moves off normal, test relay H operates over its middle winding, locks over its right-hand winding and contacts c1, and short-circuits the lower winding of C to render it sluggish. At the end of the digit, relay C relapses and if the first outlet is busy, relay H remains locked over wiper P1 and completes a self-interrupting circuit for the rotary magnet RM. Relay H remains operated as long as busy outlets are encountered, a temporary locking circuit being provided in parallel with magnet RM. When a free outlet is reached, relays H, ON release, relay C operates over its lower winding and springs NP1, to switch through, and during the interval between the release of relays A, B, relay H operates again over its middle winding. If all outlets are busy, relay H is released at contacts S2 and busy-tone is supplied from lead 13, relay A being now re-connected over wipers -1 and + 1 and their last contacts. When the critical digit is dialled, springs NP1 open and relay H releases when the first contact (disconnected) in the level is reached. Relay C does not re-operate and the vertical magnet is energized over springs NP2, N2 to release the switch. When the normal position is reached, relay DA operates, switching over to the second set of wipers and short-circuiting springs NP1 so that the critical digit may be used as a second digit. On release of a connection, the release of relay H completes the release-effecting circuit of the vertical magnet as before. In the case of premature release during dialling, rotary movement takes place automatically as for a normal call until an idle outlet or the 11th contacts are reached when the release of H completes the release circuit. If the subscriber hangs up without dialling, the vertical magnet operates during the release time of B and hunting proceeds as in the case just mentioned. Testing. The switch may be busied at jack T1, stepped as desired manually by removing link T2, and released by reinserting link T2. If the manual stepping is only vertical, relays ON, H operate and rotation takes place automatically as above.

Abstract: 1,100,492. Damping vibrations. BOFORS A.B. 7 Jan., 1966 [7 Jan., 1965], No. 918/66. Heading F2S. A vibration damping device comprises at least one permanent magnet 6 having ferromagnetic end elements 7 and a series of intermediate ferromagnetic elements 9 coaxially mounted with respect to the magnet 6.

Patent GB-621228-A (GB)
Title: Frequency modulation systems
IPC: H03C3/09
Filed: 1947-01-11
Abstract: 621,228. Frequency modulation. ARMSTRONG, E. H. Jan. 11, 1947, No. 995. Convention date, Jan. 12, 1940. [Class 40 (v)] In a frequency - modulated transmitter of the kind employing a number of frequencymultiplying stages (e.g. the system described in Specification 426,227), frequency drift in the radiated wave, due to small variations at the initial oscillator, is reduced by the frequencychanging system shown in the Figure. The initial oscillator 1 feeds a heterodyne converter 19 through two paths, each of which includes an identical chain of frequency-multipliers 6 ... 11 and 13... 18. One path includes the normal phase-modulating circuit 2, 3 fed by the signal through a correcting-network 4, and the other includes a converter 20 at which the comparatively low frequency of a second oscillator 21 is subtracted from that of the final frequencymultiplier 18. The output of the converter 20 is fed through a filter 22 to the converter 19 from which a difference frequency equal to that of the oscillator 21 is derived, and is fed through any desired chain of frequency-multipliers 25 ... 29 to the radiating-aerial 31. Any accidental variations in the frequency of the initial oscillator 1 are balanced out at the converter 19, and drift in the mean frequency of the wave radiated at 31 can only be caused by variation of the frequency of the oscillator 21.
